Why carbon trading?
There is an excessive increase in the carbon dioxide (between 326-396ppm) at the global level, which causes the Green House Effect. There could be climatic changes due to global warming, increase in skin diseases, and even extinction of certain species due to such changes in the physical and chemical environment. All these are being felt at the global level. Thanks to various attempts at the international level, the release of all greenhouse gases has been banned. Various interventions and amendments in the Kyoto Protocol came about to help make this change gradual over a period of time.
